The skin on your face should soften, but you are probably young enough that that won't be an issue.
Hair? Do you mean facial hair? Many young men are clean-shaven and show little beard shadow. If you mean scalp hair, you can get an androgynous haircut.
Breast development depends on quite a few different things. If you get too much, you can bind them as do many FtM's before their top surgery.
Hip development probably won't be noticeable if you wear men's jeans or other pants.
It depends on how long you are looking to do this. If you're a freshman and expect to be on hormones and not out four more years, I think you will have problems. If this is just something to last this semester or maybe until next summer, you should be OK.
